Visit the nitecore website and check out the specs , I am not going to
bother repeating them here . In a nutshell what we have here is a 4xAA
flashlight with a Cree XP-L emitter and 5 brightness levels as well as 3
blinky modes ( SOS , Fast Strobe and Beacon ) . So just in case you have
to , you can access the blinky modes by holding down the mode button
until the light begins it's flashy mode . To change flashy modes just
hold down the mode button again ( continuous ) until the new mode begins
. And if you tire of the blinky modes just do a single press of
the mode button and you are back to the original mode ( light level you
began with ) .

To change modes one only has to push the mode button once .. And I
haven't mentioned yet that this is a two button light ? , top button is
for modes and the lower button is the on off . I have to say
the EA45S is a lot more compact than I originally thought it would be
and it does not feel that much larger in the hand than a P60 host .
Obviously the EA45S is larger than a P60 , but also what is important is
how the light feels in the hand ( in use quite possibly ) .

I popped in some Alkaline batteries into the EA45S and put some nimh on
the charger and I do like the performance on Alkaline . But I can't see
any difference between High and Turbo with the Alkaline , so very much
look forward to seeing if the nimh can impress in Turbo . But lets get
some output figures .

Alkaline :

Moon or Ultra Low = 1 Lumen

Low = 27 Lumen

Medium = 205 Lumen

High = 300+ Lumen ( Output was sagging rather quickly - Possibly due to
the batteries )

Turbo = As above

Eneloops @ 1.28v (
Stored for several months ) :

Moon = 1L

Low = 27L

Medium = 205L

High = 455L ( And holding )

Turbo = 965L ( And dropping )

Nimh @ 1.4v off the
Charger ( rested ) :

Moon = 1L

Low = 27L

Medium = 205L

High = 455L

Turbo = 836L ( Not Eneloops )

Some very interesting results for sure , especially in Turbo mode as it
looks like Turbo is very much tied to battery performance . Now lets
check out the current draw .

Alkaline :

Moon = 0.01A

Low = 0.06A

Medium = 0.43A

High = 0.75A and dropping

Turbo = ? As above

Eneloops :

Moon = 0.01A

Low = 0.06A

Medium = 0.36A

High = 0.96A

Turbo = 2.26A

Please remember all figures given are what I was able to measure ..

I have to say that the Nitecore does impress and does so using AA
batteries . Not really having anything negative to say I can in all
honesty recommend the EA45S to anyone looking for a decent LED
flashlight . This is not the cheapest flashlight money can buy but GB
had a very nice discount going and that made the Nitecore a seriously
good buy . And last I looked the deal was still on . Am I tempted
to buy this light ? , yes I am unfortunately I spent some Ozzi Banana on
pocket knives and I sort of have a few flashlights already . ( A few )
But then if a was in the market for a new AA flashlight , the Nitecore
EA45S would be at the top of my shopping list .
